Where is the missing 95% of matter in the universe?
Do dark matter and, even, black holes really exist?

Beyond Newton explores the challenges to current astronomy by scientists who have discovered that the entire volume of our galaxy is filled with diffuse clouds of magnetized plasma - electrically charged ionized particles.
